My invention relates to winding frames and is particularly suitable for frames on which bottle bobbins are wound and in which a thread guide is controlled by means of a winding cylinder having a pair of intersecting helical grooves of opposite hands which make up an endless camway for the thread guide.

It is an object of my invention to improve a winding frame of the type described with a. view to rendering it particularly simple and reliable. To this end I provide a driving member for the bobbin which is operatively connected to the winding cylinder so as to rotate at the same speed. I form the bobbin with a portion adapted to cooperate with the driving member, and mount it for rotation and free axial displacement with respect to the member.

In a preferred embodiment of my invention the driving member for the bobbin is tapered for cooperation with a corresponding portion of the bobbin and equipped with a pair of intersecting helical grooves having the same pitch and lead as the camway in the winding cylinder.

Preferably the tapered driving member and the winding cylinder are arranged side b side on a single driving shaft, and preferably the shaft on which the bobbin is mounted for rotation and free axial displacement, is pivotally connected to the frame at one end, and means are provided for holding it in a definite position.

In the drawings affixed to this specification and forming part thereof a winding frame embodying my invention is illustrated diagrammatically by way of example.

In the drawings Fig. 1 is an end elevation of the.frame,

Fig. 2 is a side elevation showing one end of she frame, viewed from the left in Fig. 1, an

Fig. 3 is a-plan view showing the means for operating a bobbin, drawn to a larger scale.

Referring now to the drawings, 1 is the frame, 24 is a beam which extends along its rear side, 25 are uprights on the beam and 21 is a reel the shaft 26 of which is adapted to be supported in open bearings at the upper ends of the uprights 25, as best seen in Fig. 1. 11 is the driving shaft of the frame which extends below and in parallel to the beam 24. 10 are friction discs on the shaft 11, and 27, 28 are a fast and a loose pulley, respectively, on the outer end ofthe shaft. 2 are bottle bobbins, with a tapered portion at their rear ends, 12 are their spindles which are mounted to rock about pivots 13 on the beam 24 at their inner ends, and 14 are slotted brackets in which the outer ends of the bobbin spindles are supported and in which they may be fixed b any suitable means (not shown) so that t e spindles are readily lifted out of their brackets if it is desired to remove or exchange a bobbin. As mentioned above, the bobbins are free to rotate and to move axially on their spindles 12. Allotted to each bobbin 2 is a bracket 3 on the frame 1 in which a shaft 4 is mounted to rotate. 5 is the winding cylinder, and 6 is the tapered driving member for the bobbin, which are both secured on the shaft 4. 7 is a friction disc on the end of the shaft 4 which projects from the rear of the bracket 3, and 8 is a spring on the shaft 4 which is inserted between a sleeve 9 on the bracket 3 and the boss 32 of the friction disc 7 so as to hold the disc engaged with the corresponding disc 10 on the driving shaft 11.

15, 15 are a pair of intersecting helical grooves making up an endless camway in the winding cylinder 5 and 23 are a pair of similar grooves making up an endless camway in the tapered driving member 6, the grooves in the cylinder 5 and in the tapered driving member 6 having the same pitch and the same lead. 20 is a slide bar of prismatic section which is secured at the rear of the bracket 3 in a suitable block 33, and 17 and 19 are slides which are mounted on the bar 20 and connected by a strip 18, so as to move in unison. 16 is a tooth or dog on the rear slide 17 which engages in the grooves 15 of the winding cylinder 5, and .29 is a thread guide on the front slide 19. In this manner the thread guide is held against edging.

22 is the thread from the reel 21 which is conducted to the thread guide 29 through an eye 30 and about a roller 31. The thread enters the helical camway 23 in the tapered driving member 6 and is movec. to and fro along the member by the guide '29 while being wound on the bobbin 2 which is rotated by the driving member 6 engaging its tapered portion. It will be understood that as the lead and the pitch of the two helical camways, 15 in the cylinder 5 and 23 the member 6, are equal, the thread 22 is conducted by the thread guide 29 in conformity with the characteristics of the two camways.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

In the claims aiiixed to this specification no selection of any particular modification of the invention is intended to the exclusion of other modifications thereof and the right to subsequently make claim to any modification not covered by these claims is expressly reserved.

I claim 1. A winding frame comprising a rotary winding cylinder having an endless helical camway, a thread guide under the control of said winding cylinder, a driving member connected to said cylinder so as to rotate at the same speed and having an endless helical camway of the same pitch and lead as the camway in said cylinder, and a bobbin adapted to engage said driving member and mounted for free rotation and free axial displacement with respect to said driving member.

2. A winding frame comprising a rotary Winding cylinder having an endless helical camway, a thread guide under the control of said winding cylinder, a tapered driving member connected to said cylinder so as to rotate at the same speed, and a bobbin having a tapered portion adapted to engage said driving member and mounted so as to bear on said member by gravity, and mounted for free rotation and free axial displacement with respect to said driving member.

3. A winding frame comprising a rotary winding cylinder having an endless helical camway, a thread guide under the control of said winding cylinder, at driving member connected to said cylinder so as to rotate at the same speed and having an endless helical camway of the same pitch and lead as the camway in said cylinder, and a bottle bobbin adapted to engage said driving member and mounted for free rotation and free axial displacement with respect to said driving member.

4. A winding frame comprising a rotary winding cylinder having an endless helical camway, a driving member connected to said cylinder so as to rotate at the same speed and having an endless helical camway of the same pitch and lead as the camway in said cylin der, a thread guide adapted to cooperate with said driving member and controlled by the camway in said winding cylinder, and a bobbin adapted to engage said driving member and mounted for free rotation and free axial displacement with respect to said drivin member.

11 testimony whereof I affix my signature.
